STX100-000 Installation Approval Test Procedure
the appropriate standards of airworthiness for the system in question. For example: it is
permissible for a VFR certified GPS to lose navigation capability while the STX100-000
is transmitting, providing that it recovers properly and promptly, but it is not permissible
for an IFR Approach certified GPS to be affected in the same way. A complete
discussion of all the standards of airworthiness to be applied in assessing EMI effects is
beyond the scope of this document.
